During … WebAug 4, 2024 · Gametes (e.g., egg and sperm) contain only one of the two copies of each gene (haploid). Gametes result from a process (meiosis) in which the two copies of each gene are randomly separated (“segregated”) so that the gametes receive one or the other but not both copies. How many alleles does a zygote have for each trait?
